There was the annoyance of not being able to watch a 15 in the cinema at the age of 13 (though we were totally grown-up enough *huff*), and the distant allure of an 18 certificate and the mysteries that lay in its presumably mind-blowing content.

The Marvel Cinematic Universe has generally kept things accessible for younger fans, but then the huge success of Deadpool showed an R-rating need not damage takings.

Now, the studio's president Kevin Feige has been explaining where Marvel is at with certificates.

Feige was asked whether they were considering making more R-rated movies, which would presumably come with more gore and steaminess, or steamy gore, or what have you.

"Currently we don't work on R-rated movies, it's not out of the question but currently, no," he said in an interview in France (via MCU Exchange).

For those of you scratching your head at the American concept of 'R-rated', there's not an exact equivalent in the UK. According to the British Film Institute, most R-rated films get a 15 certificate when they make the journey across the pond – while almost all of the Marvel films in recent years have been given a 12 or 12A.

Some of Marvel's TV incarnations have been given a 15, such as Luke Cage and Daredevil, while Iron Fist was labelled an 18 (you can see all the ratings over on the British Board of Film Classification's website).

There is an argument that says more superhero films should have higher classifications following the example of Deadpool, whose more adult-leaning elements seemed to be a key factor in its massive worldwide success.
